Unsplash utm_source hard-coded to "Companion"

[GFoley83]

Initial checklist

• I understand this is a bug report and questions should be posted in the Community Forum
• I searched issues and couldn’t find anything (or linked relevant results below)

Link to runnable example

No response

Steps to reproduce

As seen here:

uppy/packages/@uppy/provider-views/src/Item/index.tsx

Line 57 in d6156bb

href={`${file.data.author!.url}?utm_source=Companion&utm_medium=referral`}

Expected behavior

The utm_source=<your unsplash app> to be customisable via the Unsplash plugin.

Actual behavior

Value is hard-coded to utm_source=Companion.

This is preventing us from getting "Production" level approval from Unsplash given we use our own Unsplash account with self-hosted Companion.

As per their attribution guide:

When displaying a photo from Unsplash, your application must attribute Unsplash, the Unsplash photographer, and contain a link back to their Unsplash profile. All links back to Unsplash should use utm parameters in the form of
?utm_source=<your_app_name>&utm_medium=referral

The app name is set when you create your Unsplash API key.
